DETAILED DESCRIPTION

In the following detailed description, reference is made to the accompanying drawings, which form a part hereof. In the drawings, similar symbols typically identify similar components, unless context dictates otherwise. The illustrated embodiments described in the detailed description, drawings, and claims are not meant to be limiting. Other embodiments may be utilized, and other changes may be made, without departing from the spirit or scope of the subject matter presented here.

FIG. 1 illustrates an exemplary general-purpose computing system in which embodiments may be implemented, shown as a computing system environment 100. Components of the computing system environment 100 may include, but are not limited to, a computing device 110 having a processor 120, a system memory 130, and a system bus 121 that couples various system components including the system memory to the processor 120. By way of example, the processor may include a microprocessor, a central processing unit (CPU), and/or multi-core processor. The system bus 121 may be any of several types of bus structures including a memory bus or memory controller, a peripheral bus, and a local bus using any of a variety of bus architectures. Such architectures may include at least one Industry Standard Architecture (ISA) bus, Micro Channel Architecture (MCA) bus, Enhanced ISA (EISA) bus, Video Electronics Standards Association (VESA) local bus, and/or Peripheral Component Interconnect (PCI) bus, also known as Mezzanine bus.

The computing system environment 100 typically includes a variety of computer-readable media products. Computer-readable media may include any media that can be accessed by the computing device 110 and include both volatile and nonvolatile media, removable and non-removable media. By way of example, and not of limitation, computer-readable media may include computer storage media and communications media. Computer storage media may include volatile and nonvolatile, removable and non-removable media implemented in any method or technology for storage of information such as computer-readable instructions, data structures, program modules, or other data. Computer storage media may include, but are not limited to, random-access memory (RAM), read-only memory (ROM), electrically erasable programmable read-only memory (EEPROM), flash memory, or other memory technology, CD-ROM, digital versatile disks (DVD), or other optical disk storage, magnetic cassettes, magnetic tape, magnetic disk storage, or other magnetic storage devices, or any other medium which can be used to store the desired information and which can be accessed by the computing device 110. Communications media typically embody computer-readable instructions, data structures, program modules, or other data in a modulated data signal such as a carrier wave or other transport mechanism and include any information delivery media. The term “modulated data signal” means a signal that has one or more of its characteristics set or changed in such a manner as to encode information in the signal. Communications media may include a wired media, such as a wired network and/or a direct-wired connection, and/or a wireless media, such as acoustic, RF, optical, and infrared media. Combinations of any of the above may also be included within the scope of computer-readable media.

The system memory 130 includes computer storage media in the form of volatile and nonvolatile memory such as ROM 131 and RAM 132. A basic input/output system (BIOS) 133, containing the basic routines that help to transfer information between elements within the computing device 110, such as during start-up, is typically stored in ROM 131. RAM 132 typically contains data and program modules that are immediately accessible to or presently being operated on by processor 120. By way of example, and not limitation, FIG. 1 illustrates an operating system 134, application programs 135, other program modules 136, and program data 137. Often, the operating system 134 offers services to applications programs 135 by way of one or more application programming interfaces (APIs) (not shown). Because the operating system 134 incorporates these services, developers of applications programs 135 need not redevelop code to use the services. Examples of APIs provided by operating systems such as Microsoft's WINDOWS® are well known in the art.

In an embodiment, an information store may include a computer storage media. In a further embodiment, an information store may include a group of digital information storage devices. In another embodiment, an information store may include a quantum memory device.

The computing device 110 may also include other removable/non-removable, volatile/nonvolatile computer storage media products. By way of example only, FIG. 1 illustrates a non-removable non-volatile memory interface (hard disk interface) 140 that reads from and writes to non-removable, non-volatile magnetic media, a magnetic disk drive 151 that reads from and writes to a removable, non-volatile magnetic disk 152, and an optical disk drive 155 that reads from and writes to a removable, non-volatile optical disk 156 such as a CD ROM. Other removable/nonremovable, volatile/non-volatile computer storage media that can be used in the exemplary operating environment include, but are not limited to, magnetic tape cassettes, flash memory cards, DVDs, digital video tape, solid state RAM, and solid state ROM. The hard disk drive 141 is typically connected to the system bus 121 through a non-removable memory interface, such as the interface 140, and magnetic disk drive 151 and optical disk drive 155 are typically connected to the system bus 121 by a removable non-volatile memory interface, such as interface 150.

The drives and their associated computer storage media discussed above and illustrated in FIG. 1 provide storage of computer-readable instructions, data structures, program modules, and other data for the computing device 110. In FIG. 1, for example, hard disk drive 141, is illustrated as storing an operating system 144, application programs 145, other program modules 146, and program data 147. Note that these components can either be the same as or different from the operating system 134, application programs 135, other program modules 136, and program data 137. The operating system 144, application programs 145, other program modules 146, and program data 147 are given different numbers here to illustrate that, at a minimum, they are different copies. A user may enter commands and information into the computing device 110 through input devices such as a microphone 163, keyboard 162, and pointing device 161, commonly referred to as a mouse, trackball, or touch pad. Other input devices (not shown) may include a joystick, game pad, satellite dish, and scanner. These and other input devices are often connected to the processor 120 through a user input interface 160 that is coupled to the system bus, but may be connected by other interface and bus structures, such as a parallel port, game port, or a universal serial bus (USB). A monitor 191 or other type of display device is also connected to the system bus 121 via an interface, such as a video interface 190. In addition to the monitor, computers may also include other peripheral output devices such as speakers 197 and printer 196, which may be connected through an output peripheral interface 195.

The computing system environment 100 may operate in a networked environment using logical connections to one or more remote computers, such as a remote computer 180. The remote computer 180 may be a personal computer, a server, a router, a network PC, a peer device, or other common network node, and typically includes many or all of the elements described above relative to the computing device 110, although only a memory storage device 181 has been illustrated in FIG. 1. The logical connections depicted in FIG. 1 include a local area network (LAN) 171 and a wide area network (WAN) 173, but may also include other networks such as a personal area network (PAN) (not shown). Such networking environments are commonplace in offices, enterprise-wide computer networks, intranets, and the Internet.

When used in a LAN networking environment, the computing system environment 100 is connected to the LAN 171 through a network interface or adapter 170. When used in a WAN networking environment, the computing device 110 typically includes a modem 172 or other means for establishing communications over the WAN 173, such as the Internet. The modem 172, which may be internal or external, may be connected to the system bus 121 via the user input interface 160, or via another appropriate mechanism. In a networked environment, program modules depicted relative to the computing device 110, or portions thereof, may be stored in a remote memory storage device. By way of example, and not limitation, FIG. 1 illustrates remote application programs 185 as residing on computer storage medium 181. It will be appreciated that the network connections shown are exemplary and other means of establishing a communications link between the computers may be used.

FIG. 1 is intended to provide a brief, general description of an illustrative and/or suitable exemplary environment in which embodiments may be implemented. An exemplary system may include the computing system environment 100 of FIG. 1. FIG. 1 is an example of a suitable environment and is not intended to suggest any limitation as to the structure, scope of use, or functionality of an embodiment. A particular environment should not be interpreted as having any dependency or requirement relating to any one or combination of components illustrated in an exemplary operating environment. For example, in certain instances, one or more elements of an environment may be deemed not necessary and omitted. In other instances, one or more other elements may be deemed necessary and added.

In the description that follows, certain embodiments may be described with reference to acts and symbolic representations of operations that are performed by one or more computing devices, such as the computing device 110 of FIG. 1. As such, it will be understood that such acts and operations, which are at times referred to as being computer-executed, include the manipulation by the processor of the computer of electrical signals representing data in a structured form. This manipulation transforms the data or maintains them at locations in the memory system of the computer, which reconfigures or otherwise alters the operation of the computer in a manner understood by those skilled in the art. The data structures in which data is maintained are physical locations of the memory that have particular properties defined by the format of the data. However, while an embodiment is being described in the foregoing context, it is not meant to be limiting as those of skill in the art will appreciate that the acts and operations described hereinafter may also be implemented in hardware.

Embodiments may be implemented with numerous other general-purpose or special-purpose computing devices and computing system environments or configurations. Examples of well-known computing systems, environments, and configurations that may be suitable for use with an embodiment include, but are not limited to, personal computers, handheld or laptop devices, personal digital assistants, multiprocessor systems, microprocessor-based systems, set top boxes, programmable consumer electronics, network, minicomputers, server computers, game server computers, web server computers, mainframe computers, and distributed computing environments that include any of the above systems or devices.

In another example, the decision module may draw on the same data or indicators as the countermeasure engine 1812, but require a level of malware activity and/or presence before the criterion is met for distribution. For example, while the countermeasure engine may generate a countermeasure in response to a single indication of a malware activity, and the criterion may not be met until indications of malware activity are found in at least two nodes of the plurality of networked nodes. Thus, while the countermeasure engine may generate a countermeasure in response to an indication of the Code Red II worm in one node, the criterion of the decision module may not be met until an indication of the Code Red II worm is present in two nodes.

Once the criterion is met for distribution of the generated malware countermeasure, the distribution module 1816 transmits or causes to be transmitted the generated malware countermeasure. The distribution module may transmit the generated malware countermeasure directly to a first set of nodes of the plurality of nodes 1850, or may use services of the communications module 1822 to transmit the generated malware countermeasure. The first set of nodes may be selected in any manner, including a distribution schema described above.

FIG. 29 illustrates an exemplary operational flow 1900 implemented in a computing device operable to facilitate communication of a packet to at least one node of a plurality networked nodes. After a start operation, the operational flow moves to a creation operation 1910. The creation operation generates a countermeasure useable in at least substantially reducing a harm caused by a malware (hereafter “malware countermeasure”). A decision operation 1940 determines if a criterion is met for distribution of the generated malware countermeasure to the plurality of networked nodes. A dissemination operation 1960 causes a transmission of the generated malware countermeasure to a first set of nodes of the plurality of networked nodes if the criterion is met. The operational flow then moves to an end operation.

FIG. 30 illustrates an alternative embodiment of the operational flow 1900 of FIG. 29. The creation operation 1910 may include at least one additional operation. The at least one additional operation may include an operation 1912, an operation 1914, and/or an operation 1916. The operation 1912 generates a malware countermeasure in response to indicium of a malware presence. The operation 1914 detects an indication of a malware presence in at least one of the network device, and/or in a node of the plurality of networked nodes, and generates a malware countermeasure in response to the indicated malware. The operation 1916 detects a signature and/or an anomaly corresponding to a malware presence in at least one of the network device, and/or in a node of the plurality networked nodes, and generates a malware countermeasure in response to the detected signature and/or anomaly.

FIG. 31 illustrates an alternative embodiment of the operational flow 1900 of FIG. 29. The creation operation 1910 may include at least one additional operation. The at least one additional operation may include an operation 1918, an operation 1922, and/or an operation 1924. The operation 1918 identifies a malware having a presence in at least one of the network device and/or in a node of the plurality of networked nodes, and generates a malware countermeasure in response to the identified malware. The operation 1922 identifies a signature and/or anomaly indicative of a malware having a presence in at least one of the network device and/or in a node of the plurality of networked nodes, and generates a malware countermeasure in response to the identified malware. The operation 1924 generates a malware countermeasure in response to a signature characteristic of a malware having an indicated presence in at least one of the network device, and/or in a node of the plurality of networked nodes.

FIG. 32 illustrates another alternative embodiment of the operational flow 1900 of FIG. 29. The creation operation 1910 may include at least one additional operation. The at least one additional operation may include an operation 1926, and/or an operation 1928. The operation 1926 generates a malware countermeasure in response to an anomaly aspect of a malware having an indicated presence in at least one of the network device, and/or in a node of the plurality of networked nodes. The operation 1928 generates a malware countermeasure that includes at least one of: closing at least one port of a node of the plurality of networked nodes; at least substantially isolating a node of the plurality of networked nodes from a remaining plurality of the networked nodes; at least substantially isolating at least one sub-network of nodes from a remaining plurality of networked nodes; and/or at least substantially isolating a first sub-network of the plurality network nodes from a second sub-network of the plurality network nodes.

FIG. 33 illustrates a further alternative embodiment of the operational flow 1900 of FIG. 29. The creation operation 1910 may include at least one additional operation. The at least one additional operation may include an operation 1932. The operation 1932 generates a malware countermeasure that includes at least one of: at least substantially reducing a functionally of a node of the plurality of networked nodes; at least substantially reducing a communication privilege allowed a node of the plurality of networked nodes; and/or sending a notice receivable by a device associatable with a person associated with a node of the plurality of networked nodes.

FIG. 34 illustrates another alternative embodiment of the operational flow 1900 of FIG. 29. The decision operation 1940 may include at least one additional operation. The at least one additional operation may include an operation 1942, an operation 1944, and/or an operation 1946. The operation 1942 determines if a criterion is met for distribution of the generated malware countermeasure to the plurality of networked nodes. The criterion includes an indicium of malware present in at least one of the network device, and/or in a node of the plurality of networked nodes. The operation 1944 determines if a criterion is met for distribution of a selected generated malware countermeasure to the plurality of networked nodes and selects the generated malware countermeasure for distribution from among at least two generated malware countermeasures. The operation 1946 transmits the generated malware countermeasure to a first set of nodes of the plurality of networked nodes using a distribution schema if the criterion is met.

In an embodiment, the node of a plurality of networked nodes further includes another network device, a network appliance, a computing device, a desktop computing device, a laptop computing device, a mobile computing device, a host, a server, and/or a network card of a computing device. In another embodiment, the node of a plurality of networked nodes further includes a switch, a bridge, a router, an edge router, a gateway, a hub, and/or a repeater.

The at least one additional operation 1970 may include an operation 1972, and/or an operation 1974. The operation 1972 saves at least one generated malware countermeasure to an information store. The operation 1974 causes a transmission of a packet to at least one node of the plurality of networked nodes.

In another alternative embodiment, the network device includes means 2050 for causing a transmission of a packet to at least one node of the plurality of networked nodes.

Those having skill in the art will recognize that the state of the art has progressed to the point where there is little distinction left between hardware and software implementations of aspects of systems; the use of hardware or software is generally (but not always, in that in certain contexts the choice between hardware and software can become significant) a design choice representing cost vs. efficiency tradeoffs. Those having skill in the art will appreciate that there are various vehicles by which processes and/or systems and/or other technologies described herein can be effected (e.g., hardware, software, and/or firmware), and that the preferred vehicle will vary with the context in which the processes and/or systems and/or other technologies are deployed. For example, if an implementer determines that speed and accuracy are paramount, the implementer may opt for a mainly hardware and/or firmware vehicle; alternatively, if flexibility is paramount, the implementer may opt for a mainly software implementation; or, yet again alternatively, the implementer may opt for some combination of hardware, software, and/or firmware. Hence, there are several possible vehicles by which the processes and/or devices and/or other technologies described herein may be effected, none of which is inherently superior to the other in that any vehicle to be utilized is a choice dependent upon the context in which the vehicle will be deployed and the specific concerns (e.g., speed, flexibility, or predictability) of the implementer, any of which may vary. Those skilled in the art will recognize that optical aspects of implementations will typically employ optically-oriented hardware, software, and or firmware.

In addition, those skilled in the art will appreciate that the mechanisms of the subject matter described herein are capable of being distributed as a program product in a variety of forms, and that an illustrative embodiment of the subject matter described herein applies equally regardless of the particular type of signal-bearing media used to actually carry out the distribution. Examples of a signal-bearing media include, but are not limited to, the following: recordable type media such as floppy disks, hard disk drives, CD ROMs, digital tape, and computer memory; and transmission type media such as digital and analog communication links using TDM or IP based communication links (e.g., packet links).

It will be understood by those within the art that, in general, terms used herein, and especially in the appended claims (e.g., bodies of the appended claims) are generally intended as “open” terms (e.g., the term “including” should be interpreted as “including but not limited to,” the term “having” should be interpreted as “having at least,” the term “includes” should be interpreted as “includes but is not limited to,” etc.). It will be further understood by those within the art that if a specific number of an introduced claim recitation is intended, such an intent will be explicitly recited in the claim, and in the absence of such recitation no such intent is present. For example, as an aid to understanding, the following appended claims may contain usage of the introductory phrases “at least one” and “one or more” to introduce claim recitations. However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles “a” or “an” limits any particular claim containing such introduced claim recitation to inventions containing only one such recitation, even when the same claim includes the introductory phrases “one or more” or “at least one” and indefinite articles such as “a” or “an” (e.g., “a” and/or “an” should typically be interpreted to mean “at least one” or “one or more”); the same holds true for the use of definite articles used to introduce claim recitations. In addition, even if a specific number of an introduced claim recitation is explicitly recited, those skilled in the art will recognize that such recitation should typically be interpreted to mean at least the recited number (e.g., the bare recitation of “two recitations,” without other modifiers, typically means at least two recitations, or two or more recitations). Furthermore, in those instances where a convention analogous to “at least one of A, B, and C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, and C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). In those instances where a convention analogous to “at least one of A, B, or C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, or C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.).

The herein described aspects depict different components contained within, or connected with, different other components. It is to be understood that such depicted architectures are merely exemplary, and that in fact many other architectures can be implemented which achieve the same functionality. In a conceptual sense, any arrangement of components to achieve the same functionality is effectively “associated” such that the desired functionality is achieved. Hence, any two components herein combined to achieve a particular functionality can be seen as “associated with” each other such that the desired functionality is achieved, irrespective of architectures or intermedial components. Likewise, any two components so associated can also be viewed as being “operably connected,” or “operably coupled,” to each other to achieve the desired functionality. Any two components capable of being so associated can also be viewed as being “operably couplable” to each other to achieve the desired functionality. Specific examples of operably couplable include but are not limited to physically mateable and/or physically interacting components and/or wirelessly interactable and/or wirelessly interacting components.
